Energy of signed graphs and the vertex cover number

Aniruddha Samanta, Deepshikha, Kinkar Chandra Das

The energy $E (Γ)$ of a signed graph $Γ = (G, σ)$ is the sum of the absolute values of the eigenvalues of its adjacency matrix $A (Γ)$ . In this article, we prove that $\mathca…

Unifying adjacency, Laplacian, and signless Laplacian theories

Aniruddha Samanta, Deepshikha, Kinkar Chandra Das

Let $G$ be a simple graph with associated diagonal matrix of vertex degrees $D (G)$ , adjacency matrix $A (G)$ , Laplacian matrix $L (G)$ and signless Laplacian matrix $Q (G)$ . Recently,…

On walk-regular graphs and optimal duals of frames generated by graphs

Deepshikha, Aniruddha Samanta

Erasures are a common problem that arises while signals or data are being transmitted. A profound challenge in frame theory is to find the optimal dual frames ( $O D$ -frames) to mini…
